The burgers at the Hole in the Wall are by far the best burger I've had in Dallas. However, don't expect it quick and don't expect to have a lot of room to eat it inside. This place gets packed and most people aren't eating. If you hang out long enough, you will usually get a space at the bar. People at the tables don't tend to move to often. You would think this place would be much cheaper than it is. They usually only have 1 person working the bar so be prepared to have a relaxed attitude. Also, they charge you $5 per person at the door for their ""annual fee"", which often times they will charge you every time you go there. The parking is terrible. Sometimes, they will have a band there and the cover will be more than $5 dollars, so check and see whats happening that night if you can. Their blues is great. The people watching is fantastic. The patio is roomy and they have a huge fenced in yard with tables. The people are friendly. You have to go to this place at least once. But as previously stated, you MUST come with a relaxed non-hurried attitude.
Pros: hamburgers, blues, people watching, patio
Cons: parking, location, ""annual fee"", seating
