Arcadia is a small city, and it's easy to walk between restaurants. However, if you prefer to drive, there is plenty of street parking available. Expect to pay around $5 for parking, and be sure to read the signs for any restrictions.
If you have more time, consider visiting Westfield Santa Anita, an upscale mall with a variety of shops and restaurants. If you have less time, skip the dessert stop and head straight to Tasty Garden for an early dinner.
