I just bought lunch from this La Prep location and was not at all impressed with the service that I received. The fact that they gave me the wrong sandwich is bad enough, but even more alarming is that it took 3 people over 10 minutes to figure out how to make a latte. When they finally passed me my "beverage", they giggled and informed me that they actually had no idea how to make a latte. Upon returning to my office, I discovered that it was completely undrinkable - absolutely disgusting.
I would suggest that this location should focus on their training of the equipment as they shouldn't be advertising that they sell lattes if they're actually not capable of making them correctly.
