A five-dollar shake doesn't seem as unreasonable as it did in 1994, when Vincent Vega and Mia Wallace sipped a frosty vanilla at Jack Rabbit Slim's. Almost 10 years later, you'd be hard-pressed to find a cheaper shake anywhere, except maybe a drive-thru window. But it is still just milk and ice cream. So when you order a shake at the beloved Pasadena sandwich shop Connal's, don't expect frills — the ice cream isn't homemade and it isn't organic; they don't put bourbon in it or anything — just milk and ice cream, mixed together in surprisingly perfect proportions and served in a Styrofoam cup. Priced both on size and flavor, the biggest and most expensive of which sets you back a bit less than $5, after tax. Mrs. Wallace can get her Martin & Lewis for around $3. 1505 E.
