Ruben's Tacos - a little trailer being towed by what looks like a Ford Expedition SUV is routinely parked on the north side of Santa Monica Blvd. between Westgate and Armacost and seems to do big business when I bike by. I normally pass them on my outbound leg between 2:10 and 2:30 AM and I went out of my way on the return leg this morning at 3:40 AM and they were still there. Anyone tried them? I intend on stopping one of these mornings to give them a try, and if I do I'll post about it.
