I visited once and will probably not go back. Unfortunately Starbucks has a better corner on this market, and that's not saying much. Croissants were OK-flaky enough but not rich and buttery like you'd hope. They offer a wide variety of fillings, which seems very enticing, until you try them. Stingy remnants of fillings (and I tried 3).
I give 3 stars based on the fact that they weren't terrible and I was offered a free croissant, given that it was the end of the day and they were going to be getting rid of a bunch. Check it out but don't get your hopes up too high.
