A liquor store can be more than a store that sells liquor, and when there is one, or more than one, at every cross street, it had better be -- if it wants to survive. Hence this liquor store-abundant stretch of Guerrero, where, if you haven't dropped by Pay & Save Liquor and Grocery at 18th in a while, the clerk may tell you he misses you, his eyes pleading for your return. Of course, you won't have the heart to inform him you've been patronizing Ice Cream, Wine and Liquor up on 19th, where piroshkis, sandwiches, corn dogs, and pastries overshadow the pint-sized selection of actual booze. But there's plenty of hard stuff at the Guerrero Market across the street, and though we do miss F&G Grocery, its proprietors' retirement has helped us get closer to the fellow who runs the 20th and Guerrero Market, across the street. There are no liquor stores on Guerrero and 21st. But the Pride Superette, on 22nd, makes up for this, as do the friendly folks at the 23rd and Guerrero Market. And no, Jump Start Coffee and Grocery on 24th isn't technically a liquor store (no liquor), but the sandwiches are so damn good we decided to include it too.
