We enjoy the Lakeside for breakfast, lunch or brunch about every month or so. This review will include (at the end) some points that others have not covered.
As most reviewers say, the wind-protected, on-the-water view is awesome. The location next to the watercraft rentals (all human or wind powered), and trails, and the historic Rengstorff House make the Lakeside Cafe a no-brainer choice for food and beverage!
Note: place your order and collect your beverage at the counter; take your order number and park it on your table. Meals are delivered and tables bussed, but there's not really any wait staff. Because staff do bring your meal and condiments, and they do bus your dirty dishes and keep the table clean, we do leave a small tip, although many folks do not.
There are specials on the daily menus along with a moderate range of fixed choices. The food is good - not outstanding, but tasty and satisfying - actually the desserts are awesome; portions are on the adequate-not-large side; service is fast and friendly, so you food is fresh and/or hot.
If you like Geocaching, you'll find some good caches along the hiking trails in Shoreline park.
If you have youngsters along, check out the boat-shaped play area near the Lakeside.
If you enjoy kite flying, you'll find parking on your right, just as you pass through the gate (free) for Shoreline Park.
Driving to the cafe is recommended, as It's a bit of a hike from the park entrance to the Lakeside Cafe, which is at the very end of the road in the park. Don't confuse this with Michael's restaurant which is on the golf course before you reach the lake!
Have a great time - I'll bet you'll want to go back and visit!
