If you don't want to wait, it's best you go there before 6pm, or any time on weekdays.
(You can also call and see if it's crowded)

My suggestion is, if you crave something and don't want to miss it, call and ask them before you go. (There can be groups of people ordering 20 beef tan skewers for each table, seriously.)
About the items on the wall, yes it is hard to read English since they are so tiny. If you are willing to read all that, prepare your glasses and take a walk. I would check yelp first since many items on the wall are already introduced WITH pictures (although prices are often wrong).
But still, servers can help you to pick so tell them what you feel like eating today. Servers there eat their food too so they can tell you what they think about the item you're about to order.
Lastly, it's better if you tell the server about your allergy or veganism.
(i.g. Jalapeno fried rice comes with some shrimp heads on its plate.)
Hope this helps!
