If I recall correctly, the reincarnation of Alfalfa's in Boulder was launched on Earth Day several years ago. The celebration of its anniversary, more conveniently placed on the weekend, is therefore called its b'earthday. That will be happening in Boulder tomorrow from 11 am to 4 pm, so you can also tie it in with a stop at the Boulder Farmers' Market a block away, so long as you do that part before 2 pm. Here's what Alfalfa's says:
