Thanks!

Las Vegas is a pretty big place, whereabouts are you staying? North strip, south strip, off strip? I assume you will be walking or taking short cab rides to dinner, no car to get off the strip and explore?

That's right, we will be carless. We are staying at the MGM Signature, so I guess that is south strip? We are all Las Vegas newbies, so I am spending this day stuck inside because of Hurricane Sandy doing some research and learning about what a big place LV actually is.

We are still interested in Jasmine and also read good things about Mon Ami Gabi at Paris. We would love to do one meal outside with a view of the fountains.

We would also love to do a meal at the MGM Grand on Sunday night (we will be exhausted after our big presentation).

I have recently been to Vegas and stayed at the Paris and I have to say we loved Mon Ami Gabi. We had breakfast there each morning and one dinner. It was a lovely way to start the day sitting outside, enjoying the open air and people watching. Had no complaints about service or food. We sat just inside for our dinner so we still had the views outside and could see some of the Bellagio fountain display. I didnt want to sit close to the casino area when we ate. For our last meal before we flew out we had lunch at Eiffel Tower Restaurant. It was a late lunch so we had a perfect view of the fountains when they started. $100 for 2 without tip but it was a wonderful way to say goodbye to America.
If you have time google the menus. All of the casinos have the menus online for their eating establishments. You get an idea of what is available and their prices. You can eliminate a lot and go from there. I would avoid anything that mentions a trendy bar as it will probably have loud background music.
Suggest making a booking for Mon Ami Gabi if you want an outside table otherwise you may have a wait for a table. Also the fountains dont start until 3pm if you are wanting to view them at the same time. It is also not a perfect view because of the palm trees across the road.
Hope you have a wonderful trip.

The best meal we had in Las Vegas during our 2012 trip was at L'Atelier de Joel Robuchon at the MGM Grand http://www.mgmgrand.com/restaurants/atelier-joel-robuchon-french-restaurant.aspx
The restaurant is small, quiet, non-stuffy and the food exquisite. Reservations are a good idea.

I'm not sure if it's changed, but when we ate at Mon Ami Gabi the last time we were in Vegas (a little over a year ago) they did not take advance reservations if you wanted to sit outside on the patio.

It was strictly first come, first served - so we put our names on the list at about 6:15 p.m. and we were seated at around 7:40. They give you a buzzer that allows you to wander some in the casino, but the range is not that extensive.

We were lucky and got a table right up along the railing, centered directly across from the fountains. The patio was a bit crowded as I'm sure they try to fit as many tables out there as they can.

Thank you for all the inside tips, especially on Mon Ami Gabi, which is looking like the winner for our group.
