Huge portions, friendly staff, solid food and a decent bloody mary at a reasonable price.
We have been many times and tried many things. If you are going for brunch, expect to wait. As for food, we have tried pretty much everything and the best dish is likely the Sage Chicken Benedict. The hash plates are solid and (being I like sweet breakfast) the french toast and pancakes are also good.
Go to Hash House a GoGo for a large breakfast with a large bloody mary and expect to pay a very reasonable bill when you're done. Is it the best breakfast ever? no. But you would have a hard time finding a better all around breakfast deal and if you go in with the right expectations, I'd be surprised if you didn't enjoy the meal.
