Never been to Robust Cigar, buy you'll have a good experience at Marty's. Friendly staff (owner Rio, Nicky our Jeff are usually behind the counter) and friendly customers. Also in Glendora is Glendora Cigars at 614 Rt. 66. Decent humidor (buy only a 1/4 of what Marty's has) and a large, but sparse, smoking lounge. There's also Cigars By Chivas in Pasadena, but I hear the prices are high.
