From I-10, take exit # 103A onto Evangeline Throughway (Route Evangeline), a divided highway, heading South.
Continue South on Evangeline several miles through town to the 7th traffic light (I think) where Pinhook Road crosses.
This is a fairly big interesction with gas stations on three corners. (BP, Exxon, and Conoco)
Turn left and travel a couple of miles to the 3rd traffic light (I think) where Carmel Drive and Breaux Bridge Road
intersect with Pinhook (Route Pinhook Est). On the near right hand corner is a curved metal 'Quonset Hut' building housing an oil change place.  
There will be a sign reading "Mulates 6 Mi. Ahead" pointing to the right. Turn right onto Breaux Bridge Road (LA 94)
and proceed 6-7 miles to the outskirts of Breaux Bridge. On the right, just before the second set of railroad tracks
you'll see Mulate's. There will be a lighted sign out front as well as on the front of the building listing that night's
band. If you miss Mulate's, LA 94 will deadend into LA 31 in Breaux Bridge.
LA 94 is an interesting trip in itself. You'll pass through or by wide-ranging cross-section of Acadian rural life, including:
a Catholic convent; a wild bird refuge; an oil field; a junk yard; a moto-cross track; some honky tonks;
truck stops; an industrial park; an adult video store; and a boudin and Andouille shop.
