Proper formatting

[EmptyStreets]

Hello,

What would be the proper syntax for the following feed:

<Title>Test Import Menu</Title>

    <contentBuilder>

        <MatrixBlock>
            <restaurant>Test Import</restaurant>
        </MatrixBlock>

        <MatrixBlock>
            <heading>Appetizers</heading>
        </MatrixBlock>

        <MatrixBlock>
            <description>Tasty appetziers</description>
        </MatrixBlock>

        <MatrixBlock>
            <subheading>Subs and sandwiches</subheading>
        </MatrixBlock>

        <MatrixBlock>
            <description>Made To Order Sandwiches</description>
        </MatrixBlock>

        <MatrixBlock>
			<menu>
				<items>Chicken Salad</items>
				<itemsDescription>Sandwich</itemsDescription>
				<itemsPrice>2.49</itemsPrice>
				<items>Twisted Brunch</items>
				<itemsDescription>Grilled</itemsDescription>
				<itemsPrice>1.49</itemsPrice>
			</menu>
        </MatrixBlock>

    </contentBuilder>
</entry>

Currently it creates defined menu items but imports only the first element's price and description across all entries.

Please advise.
