This past weekend, some friends of mine were talking about the high turnover of restaurants downtown. Some places seemed to only last a few scant months while others disappeared shockingly after a few days, like a kidnapping victim in a new country. And then we cracked the code. Correction: I cracked the code. To be a successful lunch establishment, you only have to pass one test and that test has only one rule: can you eat it one handed? Soups, salads, bottomless pasta bowls are all well and good, but they fail the test. And the beauty of the one-handed rule? It frees up your other hand to receive congratulatory high-fives. Yes!
