Visited OSS (Open Source Sausages) Madison on a Sunday afternoon for an early dinner and we were impressed from the start. The building looks old but renovated very nicely. Has a trendy 'gears' motif that is nice and welcoming.
We were greeted as we walked in and checked out the ordering board of a selection of various sausages and sandwiches. Very creative menu going from regular sausages (hot dog, bratwurst, polish) to upscale combinations like a Banh Mi and a Drunky Ducky. SO many choices - I went with the Chicago Hot Dog (I know boring right...) and my wife got the Smoked Brat. The Chicago dog was very tasty, good sausage - but the bun to meat ratio seemed a bit off. My wife thought her's was ok too but probably wouldn't go with smoked next time as the flavor wasn't her style and the casing was a bit tough. We also ordered a special of the day, Buffalo Cheese Curds! Yum! those were really good and another unique idea.
What slight shortcomings there were in taste were more than made up by service and enthusiasm. The guy that took our order was very friendly and helpful. He brought the food out to us and even check on us to see if we needed anything else. Another manager/owner stopped by later and say HI as well and told us about a new outdoor patio/garden they would be adding very soon.
We were really happy to have tried OSS and plan to return to try other menu options as well as check out the patio when its done. They guys running this place are doing things right and adjusting to make people happy along the way. Looking forward to stopping by again soon.
