(Visited 11/2010): Grumpy Bulldog is located in on the south side of downtown Naperville on W. Jackson, a couple miles off I-88. Street parking is available pretty much in all directions. The place is relatively small, with the bar on the left side and some high tables elsewhere. The decor includes brick walls, brewery stickers and the like. There were a lot of locals present on the weekday evening we visited. The bar has about 11 taps and over 50 bottles. Draught offerings include Kasteel, Two Brothers, Lagunitas, Southern Tier and Goose Island. As for bottles some breweries represented include Goose Island, Two Brothers, New Belgium, Tyranena, North Coast, DFH, Ska, Founders and more. Service at the busy bar was pretty good. There did not seem to be a lot of people there for craft beers but the bartender was cordial and knowledgeable enough. We did not try any food on this visit. Overall this is a pretty fun spot to hit in the area.

The only craft beer bar in Naperville. The ambiance depends on the time of day. It is a nice place to grab a pint after work but later on the bar turns into a college bar. The food is also lacking in quality. The selection is generally dominated by big hoppy IPAs from various craft brewers. There are a few Belgian offerings. Overall a nice selection and better than any other bar in the area.

It was...alright. I’m going to try it again though, I might have just caught it on an "off night"

I think this place if fantastic. The bartenders were very friendly (and somewhat knowledgeable). A small place, but clean and busy. Lots of good selections on tap. Prices a little high, but normal for downtown Naperville. The best part though is that you can sample anything on tap for free... even the Goose Island Bourbon Barrel Stout. Good tap selections, with bottles being a little more limited, yet still unique. Didn’t try the food. All in all, the best place to enjoy a beer in Naperville by far!

Great addition to downtown Naperville. Small, narrow place with exposed brick walls. A couple t.v.’s above the bar showing sports. Service was friendly and prompt and while not very knowledgeable about beer the waitress was trying hard. Decent number of taps (10 or so)though their beer list only had about half of the taps listed so make sure you check out the taps which is not hard as the place is about 20 feet weide in total. Bottle selection is varied but full of good to great beers with some Belgians, German, and a large contingent of American micros. Prices are reasonable and there were some specials on a Wednesday evening. Some of the bottles seemed a little over priced while others seemed right in line or well priced. Food was better than expected everything seemed to be made with fresh high quality ingredients and featured a good amount of spicy items which is a plus in my book. Lacks a little in character but its new and the owners seem to want to do something good here. Is a loud, crowded, rowdy mess on Friday and Saturday evenings so don’t go at these times if you want to relax or have a conversation with the staff.

Finally!!!!A bar in Naperville that has everything a beer-lover would want. Excellent beers and equal service. Went in after the GB was open and was treated to a great eating/drinking night. Alpha King and Gumballhead on tap was a treat. Also Left Hand Milk Stout was excellent. Delerium, Edmund Fitzgerald, 60 minute with possibly 90 minute coming on tap. Food was great. Try the french fries and gravy. MMM! Wait staff bends over backward to make sure you have a good experience.

The first craft beer bar in Naperville. This place has an awesome selection of draft craft such as Rogue, Tremens, Ayinger, Great Lakes, Three Floyds, Stiegl, Dogfish Head and some more. The bottle selection is even better. Old Rasputin, Augustiner, La Chouffe, Unibroue, Samuel Smith, North Coast Brewery, Founders, and many more...Service is great.
