Freddy's is just awesome- the food is reasonably priced and it's the kind of comfort food most of us crave. The inside is fun with booths and tables- but the outside is really great- like being is a giant back yard with humongous trees - and picnic tables. They often have live music- dogs are allowed and it's a great place for families.
Servers are fun as you would expect in the South Austin area of town- and they run fast to get your food to you, here.
The drinks are good- check out the daily specials both on food and the drinks (once I went the manager was doing all burgers for $5 just because it was a rainy day). They also have a great happy hour where they will add tequila floaters for $1 or so.
Definitely a fun South Austin place to go!
