Well, my GF and I went to Japonais last night and it is definitely not for kids. The food was excellent though, except for the kobe carpaccio.
Here are a few tasting menus at the Bellagio and elsewhere:
Memorial Day Buffet Event:
B and B Restaurant at the Venetian:
Valentino at the Venetian:
StripSteak at Mandalay Bay:
Aureole at Mandalay Bay:
RM Seafood at Mandalay Bay:
All-You-Can-Eat Shabu-Shabu at Shanghai Lilly (MB
Mirage Gourmet Tasting Menus:
MGM Spring Tasting Menus:
All-You-Can-Eat Sushi at Hyakumi at Caesars Palace (11-3:30pm M-F
Spring Tasting Menu at Bradley Ogden Caesars Palace:
5-Diamond Recipient Guy Savoy Caesars Palace Pre-Theatre:
Ming's Table (???) All-You-Can-Eat Sushi at Harrah's
I don't know how good of a deal many of these tasting menus are, but the deal at the Mirage Japonais restaurant in the lounge from 5-8pm daily--- a 3-course meal for two people at $45 (total)---seems like a great deal.
