This place is a hidden gem. Food quality is good and fresh. Reasonably priced foods. Be aware that menu seems vegetarian but it gives you choices of proteins. Place is very bright and spacious. Staff are very friendly and attentive. Will definitely come back!!!

BASIL & CO has reinvented itself! This upscale Thai and Vietnamese restaurant is a true winner. They have completely remodeled and renovated their restaurant to accommodate customers with discerning tastes. Their food is authentic and delicious, as always. Prices are very reasonable and portions are always generous. Servers and staff are very pleasant, attentive, and they are very glad to cater to all their customers needs. I would have to say that BASIL & CO is one of the best Thai restaurants in the SGV. Diamond Bar is lucky to have this gem in their city.

We got the eggplant basil, green curry, papaya salad with shrimp, and pineapple fried rice. Everything was wonderful, portions are quite huge, and the ingredients were fresh. My fav was the green curry and pineapple fried rice. The interior is clean and modern. I'd definitely come here again.
