Not the kind of place you expect to find in the Texas Hill Country - kind of refreshing to visit.
The good: had a great meal, very satisfying. Certainly a great place for a fun time.
The not so good: There's a lot of fat and salt that goes into this cooking, mmm good but still gives one pause. The food is all prepared on a grill (a hot, flat, steel surface), so effectively everything is fried rather than being broiled.
The "maybe": It _is_ a show. We noticed that different chefs had different techniques, presented themselves differently, and had different skills. Of the two working chefs the night we visited, ours did appear to be Japanese but there was another who was not - I haven't experienced this before. The chefs are really performing for you, and you may find you enjoy your chef's performance or not, separately from how you enjoy the food itself - but not everyone in our party was up to having shrimp tossed into their mouths, for example. The hibachi tables are set up with 8+ seats, so you'll share with others if your party isn't at least 8.
Worth going to if you have never tried it before - and I enjoyed it, as did my in-laws. Probably also really good for kids.
