I recently had the opportunity to eat at Richie's Drive Inn in Kalihi. The interior screams fast food with bright orange plastic benches.
However, folks coming to Richie's aren't looking for fine dining. They are looking for fast service, lots of food, and very little coming out of their wallets. Richie's hits all three of these objectives.
I had a cheeseburger, french fries (hot and crispy), and a strawberry slush (too bad they didn't offer ice cream with it) all for under four bucks.
