Summary: This is an excellent strategy game, the Gamezebo review is way off! Basically, this is a simplified and improved version of Restaurant Empire, which was a great idea, but way too complex. The other reviewers have described the game well, so I just want to add a few comments about some things that I would love to see in the sequel (and there will be one, right?).
Summary: This is the most enjoyable game I've downloaded in a long, long time. I love time management games, but I can only get 1/3 of the way through most of them, as they're all about speed and multiple clicking, very one-dimensional. Bistro Boulevard employs strategy, a little speed, and creativity. I cannot get enough of it! In fact, my only criticism is that it's too short for me (though that wouldn't have kept me from buying it!).
Summary: I'm very surprised at the average rating Gamezebo gave this game. I personally love it! It's very original and not at all stressful. Like others said, it's more of a "tycoon" than time management game -- very much in the style of Restaurant Empire, but a lot simpler. I really enjoyed trying to guess which ingredients made up particular recipes from all the different countries. Also appreciated all the options available to customize my restaurants.
Summary: I really enjoyed this game. It is a better version of restaurant empire. Restaurant Empire was a bit slow and repetitive, but this game is a lot more involved and you feel like you are actually working towards something. It is not as intensive as most time management games are - during the opening hours you just seat the customers, but this is more of a tycoon game (like fairy godmother tycoon, or the icecream tycoon games) - you set the restaurant up and see how well...
Summary: I agree with Cleo, this is one fun game. Very original and addictive. It's a little bit like Restaurant Empire but much simpler. I'd call it more of a strategy game than TM. At the beginning of each restaurant you will open, you hire & develop both chefs and waiters, plan (and discover/unlock) menu items and have to design the floor layout and design.
