Help! I can't get past level 8 in the harvest restaurant. I am getting very frustrated. I have tried a variety of things and noting seems to work.

I'm sure one of the faster people can give you a routine that will get a much higher score, but this is one I use that will put me about 20 points above Expert. Most of the time I am only seating 3 groups per round so I can keep everyone happy. Color matching is essential.
.
Also with only 3 groups it's really important to get the full 3 person chain. So remember that joggers never ask for dessert. If they finish, wait until the other customers have all gotten dessert before you pick up the joggers' money.
.
Also make sure you use two separate chains for money and dirty dishes. When someone finishes, click on them once (not twice). That will pick up their money but leave the dirty dishes on the table. Then get the next money. When all the money is picked up, go back and pick up all the dishes.
.
I use flowers every time and the podium a lot. Usually I take orders, give drinks, do the podium once or twice, give orders, give drinks, back to the podium for two rounds, give desserts, back to the podium, pick up money, pick up dishes, back to the podium, put out flowers, back to the podium. I may do the podium twice here or just start seating people.

Slowpoke walkthrough:
.
1. flowers, then podium twice.
Lovebirds upper middle
teen boys center left
Teen girls lower left
Teen girls center middle next to teen boys
(this arrangement will give you a flirt bonus for all 3 sets of teens. If some of the teens haven't arrived yet, go ahead and seat the ones who are in line and the others will come in soon)
============================
2. 4 girls lower left
Joggers, upper middle, match red and blue at top
lovebirds lower middle
(Remember: don't take the jogger money until the other two have their desserts)
===============================
3. lovebirds upper middle
boy and dad, lower middle
businesswomen, center left
================================
4. lovebirds upper middle
joggers lower middle
2 red teen boys center left (match red)
=================================
5. Girl with a bunch of kids, mixed colors, upper middle, match the red and blue seats at the top
(yes, this is the only group for this round, we're trying to protect those high value color seats)
==================================
6. Teen boys upper middle, match red and blue
Teen girls at the top of the bar
(another flirt bonus)
===================================
7. Lovebirds upper left
Girls upper middle (match blue)
==================================
Again, use the podium a lot! This should get you just past Expert.
.
Good luck!

I can not get past this level even with the walkthrough.
Any suggestions?

Hmmm...can't seem to get Expert here. I even used the Walkthrough and I'm still coming up about 70-100 points short.

Any suggestions? :-)

I made it! Discovered I was doing something backwards in the Walkthrough...oopsies. :-o

thankyou it,s great
