A friend is getting married in Vegas and is looking for a restaurant that would be able to accommodate about 30 people, including children, for a pre-wedding dinner. Inexpensive to moderate price.
Any and all help would be appreciated.

Maggianio's is a place you might consider. The Vegas location is at the front of Fashion Show Mall, across the street from Wynn's. They have a website with menus. I attended a function there and we had about 24 people. You can choose regular dinners or "family style" .. portions were huge and very good. Price range is moderate I'd say.

Battista's Hole in the Wall. We actually ate there after my sister's wedding! It's right behind the Barbary Coast. They have many rooms, and 30 people will easily fill one of the smaller ones. It is family-friendly.

My friend just got married in Sept and held her dinner at the All American Grill in the Rio. It was really reasonably priced (under $50 pp and included wine & beer) and the portions were huge. They gave us our own private loft room which was nice. Also since the Rio is owned by Harrah's there are shuttles from Bally's, Caesar's, and Harrah's that will get you there for free. I believe that their party menus are available online at the Rio website.

I recommend Carluccio's Tivoli Gardens for yummy Italian Food. I am certain they have banquet facilities.

Thank you all so much for the suggestions. I love this forum!!

I've heard the Grand Luxe Cafe at the Venetian is good for this sort of thing. they have private dining, reasonable cost, huge portions
