One truly great thing about where I live: Pho Bo Ga (A-12 Lebreton Street). Two blocks from my front door is a Pho restaurant that is open until 4:00am. That means tasty, spicy Vietnamese soup at crazy times of night. You can get a huge bowl of tofu Pho for $6.25 and ridiculously huge bowls for a dollar or two more.
Of course, this would be more in keeping with my lifestyle if I were still a student – feeling good about myself if I was up before 10:00am. Even given my new salarydom, it is a valuable bit of local knowledge.
