Would the batter be similar to the one below? I've never had them.

Here is a link that might be useful: Batter

I read elsewhere that they thought panko was used (Japanese bread crumbs.) Anyway, the cucumber wasabi ranch dip should be easy to duplicate.

Here's one I found! Never had them!!

Beer Batter Fried Green Beans

Ingredients :

1 cup light beer
3/4 cup plus 2-3 tablespoons flour
1/2 tsp salt
1 tbl plus 1 teaspoon cumin seed
2 tsp kosher salt
1 lb green beans, trimmed (leave in long lengths)

Method :
Blend beer, flour, and 1/2 t salt until consistency of thin pancake batter. Add more flour if too thin. Let stand, covered in plastic wrap, for 1 hour and stir again. Toast cumin seed over moderate heat for 3-4 minutes or until it is fragrant and several shades darker. Grind until fine and combine with kosher salt. Heat 2" of oil in large skillet to 375F. Dip beans into batter in batches, letting excess drip off, and fry in batches for 2 minutes or until they are golden. Drain and sprinkle with salt. Keep warm until ready to eat.
Serves 6.
