Mon Ami Gabi is a neat place to eat. I go for breakfast and eat outside.
Don't limit yourself to just being at Paris. I usually have a game plan for each day. I plan what area I am going to be at and then look at options in those areas. I will do South Strip and get an LVA 2/1 buffet for breakfast at MB, MGM or MC, plan any show that I want to see around that, KA or Cher, and then look and see what dinner places like 9 fine Irishmen, Skyfall lounge for Happy Hour, etc. Then the next day I may do Downtown and have an LVA 2/1 or MyVegas 2/1 buffet for breakfast then do the LVA gaming coupons, dinner at Magnolias 2/1 etc.
Gambling on the strip is usually a losing proposition, but I still do it!! I like to go to each casino and check them out. Bellagio has the fountains, Chihuly sculpture, chocolate fountain, indoor garden exhibit, etc.
I get my show tickets before I leave, because I rarely get them comped. We have KA, Cher and LeReve already booked.
Plan, plan and plan will save you hours of frustration, money on meals, and a lot on show tickets.
