This was one of our top things we did while in Paris. We rated it higher than any restaurant - and we went to some top ones - or museum, actually. I would recommend it highly to anyone. We were able to ride the Metro with one exchange, but got a little lost as we ended up in unfamiliar territory. Still, it was great! We were able to have a great exchange of ideas with a wonderful couple. It was just so nice not being in a restaurant or hotel - very comfortable. The meal was perfect; it was filling and tasty but not too fussy, and we had a variety of sweet desserts! We feel like we got to know about the real Paris. Definitely worth the expense.
This was a GREAT value! Our tour guide was on time and friendly, spoke American English, and knew a lot about the area. It was obvious he was interested in giving us a great tour. The walking is all uphill, so wear very comfortable shoes. It was rainy, and we still had a great tour!
