I went here for dinner on a Wednesday night. We wanted to sit outside so we had to wait 45 minutes. The hostess gave us a pager but it had a small range: we were confined to one small section of the Paris casino, and it wouldn't work outside. We ended up waiting the full 45 minutes (plus about 5-10 more for good measure).
Finally we were led to our table, which was directly across from the Bellagio. Front row seats for the fountains! However, we were also right next to the wait station, so servers were congregating less than a foot from my chair for the entire meal. Awkward, and really close quarters.
Our waitress was excellent. Very friendly, clearly knew the menu backwards and forwards. I got the half order of mussels, and she accidentally put an order in for the full size- she let me know her mistake, and said of course she would only charge me for what I ordered but she wanted to warn me in case I ordered the half-size again in the future and was surprised at the size!
So the food: the free baguette and butter were great. We both got French onion soup, which was okay. Not bad, but also not great: a little sweet, way more bread than cheese, and definitely not worth $10. I wouldn't order it again. My mom got the steak classique, which was great. I got the mussels, which were mediocre. I wasn't a fan of the wine sauce, there was almost a sour note to it? Again, not terrible but I wouldn't order it again. The fries were good, but cut so thin (and so salty!) they were almost like potato chips. We didn't have any dessert, but the table next to us had the creme brulee and it looked pretty great.
I was not overly impressed with the food, but the view cannot be beat. Lots of people-watching on the Strip, and after 7 pm the Bellagio fountains have a show every 15 minutes. The food was not amazing, but I'd be willing to try it again and just order different dishes. The escargot and the roasted chicken looked promising!
