Most of our favorite Thai restaurants in San Antonio are of the casual variety, but Thai Topaz, open since 2005, offers a fine-dining experience, with white tablecloths, several small private rooms, and generously portioned dishes. The pad Thai was fresh and crunchy, while zingy curries took on all colors. Our server recommended moderate spice levels, but if you prefer more spice you can request them or do it yourself with the chile oil on the table. The tom kha, pad woon sen, and spicy noodles were all on point. If you are in the mood for a heartier meal, the kitchen serves grilled lamb chops with lemongrass-tamarind sauce and pork tenderloin medallions with Chinese broccoli. There are also plenty of vegetable  options, from fried rice to noodles, and even a few unexpected additions like the vegan Korean bulgogi made with seasoned portobello mushrooms. The mango ice cream, made in-house, is coconut milk-based and not too sweet. Beers from Asia, Mexico, and United States join a small menu of sakes and American wines. Although non-alcoholic, the four herbal iced drinks are very special, and include flavors like lemongrass and butterfly pea. The restaurant offers 10 to 20 percent discounts on entrées if you make an online reservation during non-peak hours. In case you aren’t in the mood to visit, an easy-to-use delivery menu (with party trays, too) is also available (be aware while perusing the website is that some links may be broken).
