Od's is right across the street from me, and it's the best Irish pub option in NoSco. I don't get over there regularly, but the crowds definitely vary depending on time of day. The lunch and dinnertime crowds are pretty subdued, but when they unveil the crappy cover bands around 10 p.m., the cougars come out of the woodwork and get their scary high-heeled dance skills warmed up. If nothing else, it's hilarious to watch.
The food and beverage selection is what you'd expect: Very similar to other Valley Irish spots Rula Bula and Skeptical Chymist. The Irish stew is damn tasty, but most of the crews there skip the food for the hokey atmosphere. You can't find many good bars north of the 101 in these parts, so it's worthwhile if you're in the neighborhood.
