Actually the expressway would be I-196! Ecco-Reef is on the corner of Main and Maple(?one of those tree names) in downtown Zeeland. Chris, the owner is a very nice guy and is alway ready to bargin a bit.
Ecco-reef is an extention of his hobby with his full time job being a police officer for Zeeland. The store isn't the prettiest place, but it usually well stocked and all the livestock is healthy.
His helpers there are not very knowlegable so don't ask them any questions tougher than "is that a fish?" as you might confuse them
Is it worth a trip from the east side to have a look? Sure, if you really feel the need for a drive. If you do make the trip, be sure to make time to stop by Solomen Seas in Jenison. Between the two you would have a nice day.
