I really hate seeing negative reviews for places I love to hang out. It makes me wonder what people were expecting. With that being said, I understand different strokes for different folks.
If you're looking for a cheap entertaining night, the Comedy Cave is for you. It IS a hole in the wall, but that is definitely by design. Is the food great? Not particularily but it's no worse than any pub food you'll find. I too have found the service below average, but I don't go to a comedy club for 5 star service. Do I get the food and drinks I order? You betcha. That's good enough for me. And as for those saying the staff aren't inviting and nice, I have NEVER experienced that. In fact, I've always found them somewhat humorous. And as for the entertainment, I laugh while I'm there. It's a comedy club so that's all I expect.
