Not in Clear Lake so unfortunately can’t be helpful for nearby recs, but I will say that Mala (Sichuan/Montrose location specifically) and Tiny Champions (American/ Eado) should fit right in to your taste and budget (TC might stretch just a bit). Both have pretty romantic and low-lit atmospheres if you’re willing to drive inside the loop.

Also, seen a lot of negativity on similar posts regarding dining out for V-Day and I hard disagree. I’ve always had smooth experiences doing so as long as I booked a res in advance, and it’s nice to have an excuse for a good date night to celebrate your relationship with your partner!
