Erv’s Mug Serves Friday Fish Fries and Old-School Pub Character

A Friday fish fry at Erv’s Mug can arrive with a plateful of familiar Wisconsin decisions: hand-battered cod or walleye, fried or baked fish, perhaps a combination plate, then the question of which sides belong alongside it. Fries, potato pancakes, baked beans, coleslaw and applesauce all fit comfortably into the equation, and soup can make the meal more substantial still.

This is a place built for settling in rather than rushing through a meal. Erv’s Mug combines the sociable energy of an Irish-style pub with the warm, slightly nostalgic mood of a supper club, giving diners a choice between a full restaurant table, a booth, a high-top or a seat at the bar.

Fish fry is one of the restaurant’s signature occasions, and the menu gives it more range than a single standard cod basket. Fried and baked preparations are available, as are cod, walleye and combination meals. That breadth is useful when a table cannot quite agree on the ideal Friday order.

The sides follow the old-school comfort-food logic that makes a fish fry feel like dinner rather than a quick snack. A bowl of soup before the fish, a heap of potato pancakes beside it, or a spoonful of baked beans can turn one order into a very Wisconsin sort of evening.

Friday dinner periods can be crowded, particularly around fish-fry service. The room’s pace and noise level can shift from quiet and easy for conversation to busier and more animated as the tables fill.

Erv’s Mug does not make a non-fish-fry visitor feel like an afterthought. Burgers, chicken sandwiches, wings, Reubens, crab cakes, onion rings and cheese curds give a mixed group plenty of directions to take. The menu is broad enough for a table where one person wants seafood, another wants a burger and somebody else has been thinking about a Reuben all day.

Homemade soups are a recurring pleasure here, particularly French onion and clam chowder. The French onion soup has been served with a fried bread stick, a small flourish that suits a kitchen unafraid of a little extra crunch.

Among the more unusually named choices are the Garbage Sandwich, the Hot Affair Reuben and the Red, White and Blueberry Bacon Cheeseburger. Prime rib also has a following, though the menu’s personality may be best captured by a burger with “blueberry bacon” right in the name.

Brew City fries, Buffalo wings, boneless wings and cheese curds make easy bar-table food, while the chicken club offers a more straightforward sandwich route. This is not a menu that insists everyone order alike.

Dessert is not treated as a decorative final line. The offerings are hearty, and chocolate decadence is especially rich. It is a good candidate for sharing after a fish fry or a sandwich-and-soup meal, particularly when the table has already worked through a round of sides.

The cooking here is rooted in recognizable dishes, but the menu still finds room for a few playful names and details. That balance keeps dinner from becoming too solemn, even when the portions and plates are substantial.

The bar has more than 30 beers on tap, plus bottled selections and a substantial liquor lineup. Beer drinkers can move among styles, sizes and flavors rather than being limited to a short list of predictable pours.

Cocktails have their place as well, including Old Fashioneds and drinks that call for muddled ingredients. Erv’s Mug keeps separate beer and cocktail menus, which helps the bar feel like its own destination instead of merely a waiting area before dinner.

One especially distinctive option is Imperial brand craft soda on tap. It gives nonalcoholic drinkers something more interesting than the usual fountain choice and fits the same casual, pub-minded spirit as the beer list.

High-tops, counter seating and gaming machines give the bar a different rhythm from the dining room. You can make a quick stop for fish and a drink, linger over a cocktail, or claim a table for a longer meal.

The dining and bar spaces are crowded with beer signs, liquor signs and other visual odds and ends. The effect is almost museum-like in the sense that there is always another item to notice, not in the sense of a formal collection behind glass.

Those walls give the room a lived-in, gathered-over-time look that suits the food and drink. A meal has built-in conversation starters before anyone has even opened the menu.

Decor changes with the seasons, and the Christmas setup becomes especially elaborate. It is a setting with enough personality that repeat visits can offer a slightly different visual sweep around the room.

Erv’s Mug has the pieces for several kinds of outings: a family dinner with children, a low-key date-night meal, a casual reunion or a drink-focused stop at the bar. Families and larger groups have used the restaurant for meals together, including a party of 10 that called ahead.

The seating includes an indoor dining area, booths, bar seating, high-tops and counter seating, with an outdoor patio or terrace also mentioned. Availability can vary with the time and day, but the overall setup gives the restaurant more flexibility than a single-room supper-club dining hall.

Parking is free, with a lot described as having plenty of spaces. The food focus is firmly on fish, burgers, sandwiches, soups and pub fare, while vegetarian choices are less clearly defined by the menu information available.
