Three star reviews are probably the least exciting reviews to read. The place is okay Cheese curds are good. Sausage plate is good. The Old Fashioned are surprisingly *meh*.
If you like standing in line for a long time waiting for a place to sit in a hot and crowded place, you'll love The Old Fashioned. Also if you're fan of noisy place where you'll have to scream in order for your table mates to hear you - you'll likely rate this place 5+ stars.
Personally, I like to converse. i like it when my chair isn't slammed into by other patrons trying to get in and out of their chairs... so 3 stars feels generous.
If you go, try going during "off hours." You'll have a better time.
