Cooking Classes

Cooking classes are available at a number of Hoi An's restaurants and cafes. 
Morning Glory and Red Bridge get particularly well rated but if you're after something more intimate and cheaper then find a restaurant you enjoy that offers classes. And if they don't offer classes try asking for a lesson: it's sometimes possible to arrange an ad hoc lesson — outside of peak dining hours — for the cost of the meal and $5 or $10 extra. 
Note that wherever you take your class, you're likely to be taught how to make general Vietnamese dishes, as most of the local specialities require ingredients found almost exclusively in Hoi An.
