The dark and drab atmosphere inside Grumpy's depresses me; I wouldn't say it makes me grumpy, but it does make me sad. All the colors are black or grey, the bartenders are not talkative (though the servers are friendly and attentive) and it's just generally not a bar I enjoy going to.
It does have lots of space, though, and a pretty decent location with a fair amount of street parking nearby.
People rave about the tater tots, but I could taste the "frozen" in them and got bored after three or four.
Also, the kitchen is not forthcoming about ingredients in their food. For example, none of us have been able to determine whether there's honey in the BBQ sauce (for the mock duck sandwich) or if the breads/buns they use are completely vegan. They just wouldn't tell us anything. So the kitchen staff either didn't know or didn't want to say, which is both unusual and unacceptable.
All in all, I'd rather go the 501 Club a few blocks away, which has more food options and better atmosphere.
