Buffets I couldn't stomach but tried d/t coupons:
Sahara (now closed, thank God)
Rio (Don't know why all the hype, food was blah and the place was soooo crowded)
Sams Town (even the tortilla chips were gross)
P Ho(tried bkfst last trip d/t 2 free buffets, NEVER again; who puts out almost raw bacon?!)
I'm sure I would hate others but don't try buffets that often.
Restaurants I went to only d/t coupons:
Raffles Cafe at MB (lame food, slow service)
Pasta Palace at Palace Station (not a bad place but I became ill w/meningitis the next day after eating a seafood pasta dish; bad memories)
And, like KarenTN, I will never set foot in V/P again so I won't ever eat there!
