I eat here all the time, so I figure it's about time to write a review. In all honesty, I hesitate to do this because the place is already getting very popular (crowded) and I'm afraid I have nothing but nice things to say.
Nearly all the menu is vegan, so there is a wide range of choices. Most of the warm meals consist of a grain (usually brown rice or quinoa), a wide variety of fresh organic vegetables, some nuts or seeds, and some sort of sauce. You can get these either in a bowl or as a wrap, but I always get a bowl because you can fit more veggies in it (and they do!).
I originally wasn't too keen on some of these warm dishes because the put more sauce on it then I would like (many won't mind this, but I prefer my food as unadulterated as possible -- let the veggies speak for themselves). Then I found that they were more than happy to go light on the sauce, or omit it entirely. The staff are very friendly and will do anything they can to help you make the most of your meal. My current favorite is "The Innocent", but I am also quite find of "The Fool" and "The Lover".
They also have several meal-size salads, most of which come with one of two varieties of hummus: lemon-garlic or red-lentil. I highly recommend the red-lentil, it is low-fat, protein-rich, and very tasty. On the days that I get a salad, I generally alternate between "The Explorer" and "The Sufi Poet".
There are also soups of the day, some of which are truly awesome (I love the black bean) so definitely take a look at these before you order. A cup of soup and one of their big salads makes a perfect meal.
There are also "warm cheesy wraps" on the menu, but they aren't vegan (and even if they were I wouldn't be likely to order them, I'm not a big fan of vegan cheese), so I won't say anything about them. And they have an amazing juice bar which I keep meaning to try, but I haven't yet.
The atmosphere is awesome -- full of plants and funky artwork. It has a great vibe and is a really cool place to just hang out. Unfortunately this (and the great food) have made it very popular and it can get crowded. I recommend avoiding the lunch hour rush -- go before noon or after 1:30.
The only thing that would make Life Alive a more perfect place than it already is would be some homemade whole wheat bread (currently they don't offer bread of any sort, only the whole wheat tortillas they use for the wraps).
Great food, Great staff, Great atmosphere
