I'm glad I didn't check out the reviews before I went - I wouldn't have gone! My expectations were really low, and we got cheap tix. I can see if you paid more for your tickets and only got chicken parm, pasta and sheet cake you'd be really disappointed.
Being an Italian American girl from NJ, I think they really got it right. There was even plastic on all the tables, and the place smelled sort of musty like a VFW basement - spot on! It really did feel like some of the weddings I've been to, and I even liked the food! (But I think I just really, really miss that type of East Coast Italian-American food, and I try to eat healthy at home so this was a big treat).
The show was funny and entertaining, and I got to talk to the wedding party during the cocktail party before the wedding, and even dance with the groom. I would recommend going if you can get a deal on Goldstar or Tix 4 Tonight.
