Advice – weekend on Lake Livingston

Friends,

Hope you are well. A group of us friends are planning a weekend trip to Lake Livingston. I wanted to for your advice on a few things:
– food: what would be good places (especially seafood) to go for lunch or dinner? WHen i search reddit for this, the threads that pop up are mostly about fishing

– trails: what are your favorites? the 3 that have popped up for us are: Piney woods, trinity trace, lone star hiking trail

– bike / jet ski rentals: are there any spots you'd recommend? i couldnt find any bike rentals close to the area

​

Appreciate your help and advice!
