The Wine Merchant Lang Suan is a wine bar across from the Velaa community mall in the Lang Suan area of Bangkok, selling French and Italian wine by the bottle and by the glass. Red, white and sparkling wines from several countries are available, and customers pick a bottle in the shop and taste it at the table. Staff with WSET qualifications and a sommelier recommend wines by taste and style, and wine tastings and masterclasses are held there. Drawbacks are service that forgets orders or leaves glasses empty for long periods, and rough treatment from the manager.
